BICYCLE-LOCOMOTIVE.

SPECIFICATION forming part of Letters Patent No. 444,822, dated January 20, 1891.

Application filed November 15, 1890. Serial No. 371,488. (No model.)

T0 aZZ whom it may concern.-

Be it known that I, JOHN FISH, a citizen of the United States, and a resident of Summit, in the county of Union and State of New Jersey, have invented certain new and useful Improvements in Bicycle-Locomotives, of which the following is a specification.

My invention relates to improvements in bicycle-locomotives having driving-wheels with double flanges that run upon a single rail placed between two outer rails, the three rails being about on the same plane, in connection with a pilot bogie-truck having an axle, upon the ends of which are secured fiangeless bearing-wheels, which run upon the outer rails and form a stable support to the motor when not running.

The invention also consists in the combination of a double-flanged pilot-wheel running upon the, center rail and mounted upon the outer end of the bogie-truck, which controls and determines the axial line of the bearingwheels and axle, so as to cause them to run normal with the outer rails when running around curves.

The invention also consists in a novel form of bolster-block attached to the bogie-frame by a center-pin bolt, and it is also connected to the saddle, which connects the barrels of the twin boilers. The upper part of bolsterbloek is formed on a curve with a radius hav- 1ng its center on top of center rail. The saddle is connected to top of bolster by means of two bolts with i-heads placed in grooves concentric with top of bolster. By this arrangement the position of the transverse plane of the double-flanged pilot-wheel mounted on the end of the pilot bogie-truck is governed by the direction of the line of the oenter=rail, whether it is straight or curved, and controls the axial line of the bearing-wheels, so as to run in the same direction, the truck-frame carrying the three wheels being free to swing around the center-pin of the bolster also, the transverse motion of the motor in passing around a curve, swinging inward, can move around the curved face on the top side of the bolster, thus the purpose for which the pilot bogie-truek is used being to give a stable support to the motor when not in motion has its parts so arranged that it will not offer any disturbing action upon the main drivingwheels on the center rail when they are running around a curve.

The invention also consists in the combinaof a pilot bogie-truck, bolster, and saddle, with a twin or double boiler hung below the center of the center driving-wheel shafts and each boiler outside of the driving-wheels, thus bringing the center of gravity close to the rails, and thereby causing the motor to run steadier.

I attain these-objects by the mechanism illustrated in the accompanying drawings, in which- Figure 1 represents a side elevation of the bicycle-locomotive. Fig. 2 represents a plan view of Fig. 1. Fig.3 represents end view forward of Fig. 1. Fig. 4 represents an end view of pilot bogie-truck with truck as attached to barrel of twin boilers. Fig. 5 represents a side elevation of pilot bogie-truck. Fig. 6 represents a plan view of pilot bogietruck with the double-flanged pilot-wheel and outside bearing-wheels 011 their respective rails. Fig. 7 represents apart section through line a a in Fig. 6.

Similarletters refer to similar parts throughout the several views.

In Figs. 1 and 2, A represents barrel of waist of twin locomotive-boiler; B, fire-box end of same. They are connected securely at the forward end by the frame-bracket G and bogie-trucl; saddle D. At the fire-box end they are braced by the bracket 6:. These boiler-bracket connections allow the twin boilers to be separated a sufficient distance to allow the center driving-wheels to work free and clear between them. The engineframe F is placed on top of boiler and propcrly secured thereto, carrying crank and co upling axles, driving-wheels, and steam--cylinders. II II represent bogie-trucks, one under forward end of boiler and one under foot-plate of locomotive. I I represent double-flanged pilot-wheel on pilot bogie-truck. J J flangeless bearing-wheels on pilot bogie-truck running on outer rails.

In Figs. 4:, 5, 6, and 7, K represents top plate of bogietruck secured to under side of bolster-block L,but attached so as to swing around the center-pin bolt M, which is se- IOO cured rigidly in bolster-block. Into the upper part of the bolster-block L are twogrooves N N, concentric with the upper face of. the block, into which are placed two L-headed bolts 0 O, rigidly secured to the saddle P, which is attached to the boilers; but the heads of these bolts are fitted to slide freely in the grooves of the bolster-block Ii and an elongated opening Q Q, as is shown in saddle, Figs. 6 and 7, for the center-pin nut in block allows for a transverse motion of the motor and saddle on the bolster-block.

I do not confine myself to the use of two center-rail drivingwheels on the motor, for where it is desirable to have lightness as to weight and shortness as to length one centerrail driving-wheel can be made to fulfill the conditions.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. In a bicycle-locoinotive,'a pilot bogietruck carryinga central double-flanged pilot- Wheel running on a central rail, in combination with two fiangeless bearing-wheels running upon outer rails, substantially as specified and arranged, and for the purpose as herein set forth.

2. In a bicycle-locomotive, a pilot bogietruck with central .rail pilot-wheel and outerrail bearingwvheels, in combination with a bolster and center-pin, substantially as specified and described, and for the purpose as herein set forth.

3. In a hieyele-locomotive, the twin boiler suspended below the center of and each out side of the center rail driving wheel or wheels, in combination with a pilot bogie-iruek having a double-flanged center rail pilot-wheel, and outside bearing-wheels running upon outer rails, substantially as specified, and as herein set forth.

4. In a bicycle-locomotive, the central driving wheel or wheels running upon a single rail, in combination with a bogie-truck having a double-flanged pilot-wheel and outer bearing-Wheels, substantially as specified and described, and for the purpose as herein set forth.
